..p.) facilitated glutamic acid release in and near the OVLT. The results support the view that NMDA receptor in the AV3V region modulates in a facilitative fashion the AV3V inputs to the supraoptic neurosecretory neurones...

..These results demonstrate that brainstem noradrenergic neurons mediate oxytocin release following noxious stimuli in the rat and suggest that responsible noradrenergic neurons are the A1 cells in the caudal ventrolateral medulla...

..The results suggest that an activation of NMDA receptors are required to acquire and recall but not to consolidate or retain the emotional memory associated with VP, OT and PRL responses to conditioned fear stimuli...

Facilitation of Ca2+ store-dependent noradrenaline release after an N-methyl-D-aspartate receptor antagonist in the rat supraoptic nucleus

T SaitoDepartment of Physiology, School of Medicine, University of Occupational and Environmental Health, Kitakyushu, JapanJ Neuroendocrinol 20:207-19. 2008

..Our results suggest that salusin-beta may be involved in the regulation of body fluid balance by stimulating neurohypophyseal hormone release from nerve endings by an autocrine/paracrine mechanism...

Facilitative role of prolactin-releasing peptide neurons in oxytocin cell activation after conditioned-fear stimuli

..The results suggest that nicotine acts within the supraoptic nucleus to facilitate noradrenaline release pre-synaptically. This presynaptic action may contribute, in part, to vasopressin release after nicotine...

Role of adrenoceptors in vasopressin, oxytocin and prolactin responses to conditioned fear stimuli in the rat

..p. administration of 2-B4O. These results suggest that a peripherally administered high dose of 2-B4O activates OXT-secreting neurons in the hypothalamus through activation of NTS neurons, possibly as a result of a stress response...

Involvement of prolactin-releasing peptide in the activation of oxytocin neurones in response to food intake

..These findings suggest that PrRP mediates, at least in part, the activation of oxytocin neurones in response to food intake, and that the CCK-PrRP-oxytocin pathway plays an important role in the control of the termination of each meal...

..The parvocellular and magnocellular neurones in the PVN might show different responses to central salt-loading to maintain body fluid homeostasis as a result of the modulatory role of central endogenous AVP...

..The diabetic condition and insulin-treatment may affect the regulation of PrRP gene expression via leptin and other factors, such as plasma glucose level. The diabetic condition may not impair the role of PrRP as a stress mediator...

..This review describes how prolactin-releasing peptide neurons receive information concerning both internal metabolic states and environmental conditions, and play a key role in energy homeostasis and stress responses...

..c.v. administration of NPW30 (2.8 nmol/rat). These results suggest that central NPW30 may be involved in the regulation of secretion of AVP and OXT in the magnocellular neurosecretory cells in the SON and PVN...

Possible inhibitory role of prolactin-releasing peptide for ACTH release associated with running stress

..Our studies demonstrate that OXTR plays a critical role in regulating several aspects of social behavior and may have important implications for developmental psychiatric disorders characterized by deficits in social behavior...
